arm64: dts: rockchip: Fix USB3 Type-C on rk3399-sapphire
Before this patch, the Type-C port on the Sapphire board is dead.
If setting the 'regulator-always-on' property to 'vcc5v0_typec0'
then the port works for about 4 seconds at start-up. This is a
sample trace with a memory stick plugged in:
1.- The memory stick LED lights on and kernel reports:
[ 4.782999] scsi 0:0:0:0: Direct-Access USB DISK PMAP PQ: 0 ANSI: 4
[ 5.904580] sd 0:0:0:0: [sdb] 3913344 512-byte logical blocks: (2.00 GB/1.87 GiB)
[ 5.906860] sd 0:0:0:0: [sdb] Write Protect is off
[ 5.908973] sd 0:0:0:0: [sdb] Mode Sense: 23 00 00 00
[ 5.909122] sd 0:0:0:0: [sdb] No Caching mode page found
[ 5.911214] sd 0:0:0:0: [sdb] Assuming drive cache: write through
[ 5.951585] sdb: sdb1
[ 5.954816] sd 0:0:0:0: [sdb] Attached SCSI removable disk
2.- 4 seconds later the memory stick LED lights off and kernel reports:
[ 9.082822] phy phy-ff770000.syscon:usb2-phy@e450.2: charger = USB_DCP_CHARGER
3.- After a minute the kernel reports:
[ 71.666761] usb 5-1: USB disconnect, device number 2
It has been checked that, although the LED is off, VBUS is present.
If, instead, the dr_mode is changed to host and the phy-supply changed
accordingly, then it works. It has only been tested in host mode.
